Hey guys,
I had a quick scan and couldn't really see if anyone had made this suggestion, so here it is:
I think you should have the option to get some kind of a refund for Vehicles/stations,
Instead of the delete button it should be replaced with some kind of a re-sale value for what ever you bought, say 75% of what you have spent.
This would mean you could reinvest money if you wanted to remove a service or strengthen/weaken a service.
What you guys think, Let me know.
